random boot issue with HDDs

Hi all,

I have a random issue that is easy replicated.
When I boot the PC from power-off state 2 of my hard drives are missing from Windows.
If I reboot the PC (not powering off, just rebooting) they show up when I log in.

If I shutdown and then start up again straight away the drives are missing again.

Drives show up in BIOS correctly.

When I go into disk manager with the drives missing I cant see them in disk manager.

The motherboard is a Gigabyte UD5H-Black

The two drives are connected to PS & PM SATA ports.

I have done a DISKPART DETAIL and report is attached.  Disk 5 & 6 are the two that arent showing up on fresh startup.

I am stumped here as I have no idea why they would be missing from bootup and fine with a reboot.

Any help appreciated.

Looks like they are connected through INTEL SS DSC2CW120A3 SCSI card. Just update the driver that is compatible with your OS - this will fix your problem.

Check whether you can set any timing options in the BIOS. Some disks often take time to spin-up, and if the PC boots too quickly they aren't ready yet. If you can change the timing so it takes longer to boot, it could help.

as a note... it appears both trouble drives are connected to the Marvell controller.
I have checked drivers etc and they all appear to be newest installed.
Timings in BIOS are unavailable as an option.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Then there is probably not much you can do, except maybe, if you have another SATA controller on the mainboard with spare ports, connecting them to that.

it is so weird. they were working fine before and then a hdd died and I replaced it and now they are mucking up on boot up yet a reboot fixes it.
>>   then a hdd died    <<  possibly that was not the only problem
i suggest to connect one drive at the time - and test each one with the proper manufacturer's diagnostic
i use the UBCD for this :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

**  you can make a bootable cd - or bootable usb stick

Can you confirm that the battery on the motherboard is good? Have you tried replacing it?
also - was this pc working fine before?
or did it happen after installing hard- or software?
please tell us

PC was working fine. The only issue was a drive that kept coming up as predicted failure, which I replaced. then it worked fine for a few days and all of a sudden I noticed the drives missing on boot.

motherboard is less and 5 months old. I would be surprised to find the battery at fault.

Still I would try with a new one.
can be the new drive is bad
try removing it, and see if it still happens - or test with another drive

giving you both points for helping but no real solution to the issue has been achieved. this issue still happens and all I can put it down to is a faulty controller on the board :(
